Fully synthetic oil or semi

[Jacko]

Yeah, they put semi in because its much cheaper to buy and they can charge nearly as much as they can for fully, meaning the profit margin is greater. Dealers are in business to make money not friends. It's one thing saying that your bike simply doesn't need fully synth and it's quite another to recommend you don't use it.

Cupar have only used Valvoline fully synth on mine: it's their choice, not me asking for it specifically.

Interesting that Suzuki appear to be suggesting you use 4 stroke oil in a 2 stroke crosser and somehow that premix does gears & clutch too? You've got seriously knackered seals if it does.... :wtf: Think I need some for the TS?

Now I assume that because they are being paid by Castrol they recommend Castrol's fully synthetic oil:

interesting that they recommend the same fully-synth across the whole range

Apart from in your particular bike at service time. ;)
